What should i expect to find on the second PV? (50gb) - there is only 800gb in the total volume - so I wouldn't expect to find any data on it, but should there be any "header information" at the start of the drive?When i seek to the 2tb byte in the virtual image file - its blank - no evidence of any data - is this normal?
